Specification of Letters Patent.

Application filed Angust 23, 1912. Serial No. 716,652. l

To all when "-j w13/ concern i nea im@ fr .an I, HENRY A. rin-- teren, Jr., a citizen of the United States of America, residingiat'. NewOrleans, in the parish of Orleans and State of Louisiana, have inventednew and useful Improvements in Fansof which the following` is aspecification.

`This invention relates 'to improvements in ,fans ano. has particularapplication to motor lin carrying out the present invent-ion, it

isiny purpose to'provide a fan which will havea relatively large airforcing capacity as compared withfans now 1n general use and whereby theair will be .forced laterrally aswell as forwardly of the driving motorof the fan.

Furthermore, lt aim to provide a fan which will embody among otherfeatures a plurality 'of blades radiating from a com- 'mon anis, and anumber of blades carried by each of the blades first mentioned andradiating from a'coinmon axis at right angles to the axis of the 4firstblades, each group Vof blades constituting in effect a fan unita'ndoperating to throw or force the air laterallv of thefan motor asWell as forwardlythereof. f

lditli the above and other objects in view, the invention consists inthe construction, combinationand arrangement of parte hereinafter setforth in and falling within the scope of the claims.

l'n the accompanying drawing: `.Figure 1 is a side elevation of a fanconstructed in accordance with the present invention. Fig. 2 is a planview thereof., Fig. 3 is a fragmentary sectional view of the same, partsbeing shown in elevation.

in the present instance, I have shown the fan utilized as a ceiling`fan.V `llt lis to be understood, however, that the invention in itsuseful application is not limited to any particular type of fan the samemay be employed as a wall or portable fan.

Referring now to the accompanying drawing in'detail, the numeral 1designates a hanger shaft adapted to have one end fastened to theceilingwhile the other end carries a casing 2. .arranged within thecasing 2 is the fan drivingmotor 3 which in the present instance, is inthe form of an electric motor having; the armature shaft thereofextending outwardly of the lower portieri of the casirng` 2. Keyedo1"otliei.vise

blades 7;

, secured to the projectingend ofthe armature shaft is a collarl.tnprovided with ra-v dally extending sockets '5.' Suitably fas' tenedWithin. each socket 5-.is the shank 6 of a blade?, four blades' beingshownl` in this`r` embodiment of my invention, and all of' such bladesradiating from a common axis. These blades 7, it will be noted, havea'h'elical pitch and act to force or throwthe air4 forwardly of themotor in one direction.- l

In order" to throw the air outwardly 'or radially of the. path ofmovement of the blades 7, so that` the fan, when in opera-f tion, willthrow theairflaterall-yofthe" fan motor as well asforwardly' oiwont-'wardly thereof,- I-r arrange 'at the fr'eee'nvd-j" of each bladev T, aplurality ofv blades 8,"4

radiating from a .common axis at right angles to. the-f` axis ofthefirstbl'ades, that is the liladesgf'.` vvThe blades 8 at the enterextremity of Leach'bla'de 4(2 are carried by radial sockets S) on t-he-collar 10 lteyednpon one end of a shaft-11 extending alongr the lengthof the respective blades 7 approximately centrally of the width thereofand on one side of such blade, a sleeve or the like 12 encircling theshaft and being secured to the same side of the blades 7.

lThese sleeves 12 form bearings for the re` spectivc shafts and it maybe here stated that other forms of bearings may be employed in lieu ofthe sleeves 12 without departing from the spirit of this invention.Disposed concentrically of the armature shaft and suitably fastened tothe casing 2 at the lower end thereof or otherwise supported is a crowngear 13 with which mesh pinions 1-/1- keyed to the free ends ofthetubular shaft 11 at the inner ends of the From the foregoing descriptiontaken in connection with the accompanying drawing, the construction andmode of operation of my improved fan will be readily apparent.

vWhen the driving motor is in operation, the yfan' blades 7 rotate andforce the a1r downwardly or forwardly of the driving motor, while theblades 8 `at the outer ends of the f blades 7, d ne to the pinions 14Cmeshing with the crown gear 13, throw theair laterally of the fan motoror in a direction at right angles to the direction of movement of theair under the action oftheA blades 7.

It will be seen that I have provided a fan of relatively great capacityas compared with thar class of fans heretofore construct- While I haveherein shown and-.described oneQparticular 'form of my invention by wayof illustration, it is. to bebnnderstood that ,I do not limit or confinemyself to the precise details of construction herein-described and,'delineated, as modification and variation 'mayY be: made 'within therscope of 4the claims' and without departing from the spirit fof theinvention.

claim-zv l i h Y l. A fan comprising a plurality'of blades radiatingfrom a conmon axis, and a plu rality'of bladescarried each of the firstblades and radiating from: a common axis at right .angles to the axis-ofthe firstA blades whereby the last-named blades may be rotated ina'pathat right angles tothe path of 'movement of the first blades.

2. A fan comprisiifigr a plurality of blades radiating-from. a commonaxis, a` plurality of'blades'carried by each of the rst blades 1 andradiating from a common axis at right angles to 'the axis of the firstblades whereby ytheflastnamed blades maybe driven or ro- "tated in apath atrght angles' to the pat-h et movement ofthe first blades, andmeans @common to all of said bladesifor driving /jt'he same.

, l" 3. .A fan comprisinga plurality of blades radiating from a commonaxis, a plurality of blades carried by each of the-rst blades andradiating from a commonV axis at right angles to the axis f the firstblades whereby the last-named blades may be rotated at right angles tothe path of movement of the 'first blades, and means common to all ofsaid blades for driving the same, said means comprising a driving motorfor driving the first blades, and a crown gear and pinions meshingtherewithfor driving the second- 4. A fan comprising-a plurality ofblades radiat-in from a common axis, and a plurality o. blades arrangedat the outer ends of each of the first blades. and radiating from acommon axis at right angles to the axis of the irs't blades, drivingshafts for the'last-mentioned blades and carried by the first-mentionedblades, and means common to all of said blades for driving the same.

5. The combination with a casing and a driving motor therein havinv ashaft extending b vyond the casing a an comprising a plurality of bladesradiating fromV said shaft, and a plurality of blades arranged atthe'outer ends of each of the first blades and radiating froma commonaxis at right angles to the shaft supporting the first blades, drivingshaftsv for the last-mentioned blades, a crown gear carried by saidcasing,

and `p1nions carried by said last-mentioned shafts and meshing with saidgear whereby in the rotation of the first-mentioned blades under theaction of the motor movement will be imparted to the last-mentionedblades.

In testimony whereof I allix my signature o two witnesses.
